CNTRAL HEATING Filed Sept. 50, 1931 FGA Fier Patented JulylO, 1934 UNITED STATES PATENT OFFICE 1,965,727 CENTRAL HEATI NG Franois Springu'el, Brussels, Belgium Application September 30, 1931, Serial No. %6,059 In Belgium March 2, 1931 2 Clams.

This invention relates to improvements made in the systems of central heating with water or other fluid, which are provided with electrical means or gas burners or the like, hereinafter referred to as the special heating means, for raising the temperature of the water or other fluid traversing the radiator. The present arrangement is characterized in that the said spe cial heating means heat the heating fluid so as Q to produce a movement in this fluid which shall have the same direction as the movement produced in the same heating fluid in the various units of the radiator by the central heating.

The special heating means may be placed in series with the central heating radiator, the water heated by the special heating means passing from the latter into the various units of the radiator.

The said special heating means may consist of resistances which are heated electrically, and are placed either inside or outside a heating unit in which the heating fluid is admitted at the lower part, is evacuated at the upper part and is admitted afterwards to the next units of the radiator, of the usual kind.

A partition, conduit or any other similar device may be arranged at the lower part of the special heating element, in order to prevent the entering fluid from becoming mixed with the fluid which leaves the radiator. i

Means may be provided for shutting the unit heated by the special heating means off the circuit from the outside of the special unit.

The electrical resistances may be located in a r hollow space Situated between two compartments filled with the heating fluid.

An expansion vessel may be fitted to the radiator which is provided with the special heating unit, for the case when this unit acts alone for raising the temperature of the heating fluid.

In the accompanying drawing which shows by way of example how the invention may be carried into eflect,

Fig. 1 is a vertical section through an installation provided with ordinary radiators and with radiators according to the present invention,

Figs. 2 and 3 show, on a larger scale, two elements of radiators shown in Fig. 1, provided with the special heating means.

Fig. 4 is a section along X-X of Fig. 3, and

Fig. 5 shows a modification of construction of a radiator unit provided with electrical heating means.

Referring to the drawing, 1 is a boiler or any other main heating apparatus, 2 and 3 are pipes for the circulation of the liquid from the main heating device 1 and its return after having circulated inside the radiators, 4 is a radiator provided with special electrical heating means 5, 6 is a radiator provided with special gas heating means 7, and 8 is an ordinary radiator; 9 isan expansion vessel.

Referrng to Fig. 2: the portion of the special element 10 of radiator, comprised between the upper and lower collectors of the radiator has a special section, such as shown in the drawing, the heating fluid passing through the two side compartments 11, the hollow space 12 between the inner walls 13 of the said compartments receiving the electrical heating plates 14 arranged between two insulating sheets 15 and protected by a metallic cover. One or several heating plates may be arranged along the height of said hollow space.

In the modification shown in Fig. 5, a cover' 17 is fixed on the element 10 against the hollow space 12. The said cover encloses the switches, wires and connections, ensuring the working of the electrical resistances according to requirements.

The special heating of a radiator may be carried out for a radiator independently of the central heating, if a special device is provided acting as an expansion vessel permitting the expansion of the water contained in the radiator.

The radiator may be heated by electrical resistances arranged on the outer faces of a special element. A special element 18 of the radiator 6, heated by gas, is shown on a larger scale in Fig. 3. The element 18 is provided at its lower part with a gas burner 19 or the like. The gas heated element 18 has preferably a smaller height than the other elements of the same radiator. A cover 20 is fixed to the lower part and the height of the element plus that of the cover is preferably equal to that of the other elements.

Inside the cover 20 are placed the gas burners 19, the outlet pipe 21, and the valve 22 which serves to shut the radiator special element off from the return pipe of the central heating installation. This valve 22 can be operated from the outside of the cover 20.

Above the burners are Situated tubes 23 made of Copper or other metal, placed inside the element 18 and opening at the upper part. The gases ascending in these tubes heat the fluid inside the radiator.

The present invention is not limited to the modes of construction described, and it may receive various modifications without departing from it scope.

I claim:

1. A radiator for a central heating installation, having a plurality of interconnected substantially Vertical elements communicating with each other at their upper ends, means for admitting heated liquid at the lower part of the first of said elements, means for withdrawing the said liquid at the lower part of another of said elements, means for causing the heated liquid to pass upwardly through the first element and downward through other elements before it can be withdrawn, and auxiliary heating means entirely located within the ascending liquid column of the first element, as set forth.

2. A radiator for a, central heating installation, having a plurality of interconnected substantially vertical elements communicating with each other at their upper ends, means for admitting heatecl liquid at the lower part of the first of said elements, means for withdrawing the said liquid at the lower part of another of said elements, means for causing the heat ed liquid to pass up- Ward through the first element and downwa'd through other elements before it can be withdrawn, and auxiliary electrical heating plates entirely located within the ascending liquid column of the first element in a hollow space between two compartments filled with the heated liquid, as set forth.
